i have an 07 stp and have a 36 tooth on the front and 11-28 on the back and i want to keep the 36 tooth on the front and make it a single speed but dont know wat tooth size to put on the back and i want to dj on it/ thx for your help
18t would be a good place to start, but for djing if you want some more torque you might end up going with a 17 or 16t. Try a gear in your setup which would suit for 80 to 90% of the time, and count the number of teeth on that particular cog. Sometimes it is written on them too.
